Abstract

In this paper, we propose a pattern consistency index for detecting heterogeneous time series that deviate from the representative pattern of each cluster in clustering time course gene expression data using the Pearson correlation coefficient. We examine its usefulness by applying this index to serum time course gene expression data from microarrays.

본 논문에서는 피어슨 상관계수를 이용한 시간경로 유전자 발현자료의 군집분석에서 군집의 대표적인 패턴에서 벗어나는 이질적인 패턴을 보이는 시계열을 탐지하기 위한 패턴일치지수를 제안하고, 이를 마이크로어레이 실험으로부터 얻어진 혈청 시간경로 유전자 발현자료에 적용하여 유용성을 검토해 본다.
